Equipotential grounding is the bonding of
all conductive surfaces in the room together
and to earth. This can be implemented in the
patient care environment if it is crucial to keep
all conductive surfaces at the same electrical
potential or on the same ground plane.
If an equipotential grounding system is installed,
the ground system should be tested per chapter
four of NFPA 99.
